May I'am wrong, but as far as I know, we get this error only
if we are using the CPP-domain. Since the kernel-doc parser
uses the C-domain, we should not have those error messages
(tested here with sphinx 1.4).
That said, I don't see the need to change the kernel-doc parser
eleminating the address_space tags.
Or did I missed some point?
